ASoC: amd: fix for pcm_read() error
Below phython script throwing pcm_read() error.
import subprocess
p = subprocess.Popen(["aplay -t raw -D plughw:1,0 /dev/zero"], shell=True)
subprocess.call(["arecord -Dhw:1,0 --dump-hw-params"], shell=True)
subprocess.call(["arecord -Dhw:1,0 -fdat -d1 /dev/null"], shell=True)
p.kill()
Handling ACP global external interrupt enable register
causing this issue.
This register got updated wrongly when there is active
stream causing interrupts disabled for active stream.
Refactored code to handle enabling and disabling external interrupts.
